Abstract
The utility model relates to a linear guideway pair with holders. The linear guideway pair with the holders comprises a slide way and a slide block, wherein the slide block is provided with a groove matched with the section of the slide way in shape, and the slide block is connected on the slide way by the groove and can move along the slide way in the axial direction. The linear guideway pair with the holders is characterized in that the two sides in the groove of the slide block are respectively provided with at least one track corresponding to the slide way, the two ends of the slide block are respectively fixedly connected with a first reverser and a second reverser, at least two holders are respectively connected between the first reverser and the second reverser, and the two holders respectively correspond to the cambered surfaces of two sides of the tracks in position; at least one rollaway nest is formed between the cambered surfaces of the holders and the cambered surfaces of the tracks, and balls are arranged in the rollaway nests. According to the linear guideway pair with the holders, at least one rollaway nest is formed between the cambered surfaces of the holders and the cambered surfaces of the tracks, and the balls are arranged in the rollaway nests; the holders are designed integrally, so that the linear guideway pair is convenient to install; and without the installation of screw spikes, connection hooks lock the reversers at the two ends, so that a slide block assembly can be put in the tracks for damping test.
Description
Technical field
The utility model relates to a kind of linear guide pairs with retainer.
Background technique
Along with the development of Modern Manufacturing Technology, so that traditional development along with Modern Manufacturing Technology, so that huge variation has occured traditional manufacturing industry, Numeric Control Technology, electromechanical integration and industrial robot have obtained using more widely aborning.Location accuracy, guiding accuracy and the feed speed of mechanical transmission mechanism are improving constantly simultaneously, make traditional guide mechanism that great change occur.Since beginning commercialization in 1973, linear rolling guide has replaced traditional sliding straight guide rail gradually with its exclusive characteristic, is widely used in industrial production.Adapted to machinery now for highi degree of accuracy, high-speed, energy saving and the requirement of shortening product development cycle, be widely used in the machinery that various heavy combination working machine tools, numerical control machine tool, highi degree of accuracy electrodischarge cutting machine, grinding machine, industrial robot and even general industry use.At present, the manufacturer that produces linear rolling guide abroad mainly concentrates on the U.S., Britain, Germany and Japan and other countries.Domestic manufacture view at linear rolling guide also is in the starting stage.In the prior art, because retainer adopts segmental structure to be spliced, in installation process, must consider to splice precision, if splice badly, then steel ball friction factor when rolling will increase, particularly because after friction generates heat, the expansion coefficient difference of two sections retainer causes steel ball to roll not smooth, causes mechanical failure.So, global design retainer how, and conveniently in the damping of debugging slide block, need not to assemble screw, be the technical barrier of related domain.
The model utility content
The technical problems to be solved in the utility model provides a kind of linear guide pairs that is provided with the global design retainer.
In order to solve the problems of the technologies described above, the utility model provides a kind of linear guide pairs with retainer, comprise: guide rail and slide block, described slide block is provided with the groove that matches with the sectional shape of described guide rail, described slide block is connected on the described guide rail by groove and can moves axially along described guide rail, both sides are respectively equipped with at least one track corresponding with described guide rail in the groove of described slide block, described slide block two ends are fixedly connected with respectively first, the second reverser, at least two retainers are connected to described first, between the second reverser and the position of two retainers is corresponding with the cambered surface of described track both sides respectively; At least form a raceway between the cambered surface of described retainer and the cambered surface of described track, be provided with ball in the described raceway.
Further, in order better to pin the reverser at two ends, the two ends of described retainer are provided with the butt hook that links to each other with first, second reverser respectively.
Technique scheme of the present utility model has the following advantages compared to existing technology: the retainer global design makes the easy to assembly of described linear guide pairs; And in the situation that screw is not installed, described butt hook has pinned the reverser at two ends, can put into track to slide block assembly and carry out damping test.
Description of drawings
For content of the present utility model is more likely to be clearly understood, below the specific embodiment and by reference to the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the structural drawing of linear guide pairs of the present utility model;
Fig. 2 is the structural drawing of retainer of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated:
Embodiment 1
See Fig. 1-2, a kind of linear guide pairs with retainer, comprise: guide rail 1 and slide block 6, described slide block 6 is provided with the groove that matches with the sectional shape of described guide rail 1, described slide block is connected on the described guide rail 1 by groove and can moves axially along described guide rail 1, both sides are respectively equipped with at least one track corresponding with described guide rail 1 in the groove of described slide block 6, described slide block 6 two ends are fixedly connected with respectively the first reverser 3-1, the second reverser 3-2, at least two retainers 5 are connected to described the first reverser 3-1, between the second reverser 3-2 and the position of two retainers is corresponding with the cambered surface of described track both sides respectively; At least form a raceway between the cambered surface of described retainer 5 and the cambered surface of described track, be provided with ball 4 in the described raceway.
The two ends of described retainer 5 are provided with the butt hook 5-1 that links to each other with the first reverser 3-1, the second reverser 3-2 respectively.
Obviously, above-described embodiment only is for the utility model example clearly is described, and is not to be restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all mode of executions exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
Claims (2)
1. linear guide pairs with retainer, comprise: guide rail and slide block, described slide block is provided with the groove that matches with the sectional shape of described guide rail, described slide block is connected on the described guide rail by groove and can moves axially along described guide rail, it is characterized in that: both sides are respectively equipped with at least one track corresponding with described guide rail in the groove of described slide block, described slide block two ends are fixedly connected with respectively first, the second reverser, at least two retainers are connected to described first, between the second reverser and the position of two retainers is corresponding with the cambered surface of described track both sides respectively; At least form a raceway between the cambered surface of described retainer and the cambered surface of described track, be provided with ball in the described raceway.
